This invention relates to pictorial reproductions in plaque. Theinvention has particular reference to the reproduction of works of artin metal, and relates especially to a distinct manner of finishing thesurface of the reproduction. The invention is characterized by havingthe figures of the painting or picture reproduced, embossed or-raised inproper proportion and a distinctive feature of the invention resides insilver-plating the surface, and then using a shadowing material such aslampblack or powdered carbon, for example, to fill in the depressionsand accentuate the embossed effect of the charactersor objects.

Thus, the invention is essentially embodied in a metal plaque having thecharacters or objects embossed or raised proportionately from thesurface in the casting or pressing of the plaque, and the distinctivesurface finishing which, as above mentioned, inheres preferably in a:precious metal plating by means of which the plaque is rendered muchmore attractive and also endurable.

Other objects will appear hereinafter.

f' The invention consistsin the combinations andvarrangements o f partshereinafter described and claimed.

The invention will be best understood by forming a which: y

Fig. I is a face or elevational view ofk a part of this specification,and in typical plaque of the invention mounted in.

, a plaque base is employed which is prefer-r ably composed of copper orother endurable malleable metal. The base relief may be pre-' paredeither by a casting or mould process. 'Referring particularly to Fig.,2theplaque base 4 is mounted in a suitable frame 5 and held in placeby anappropriate backing 6.

reference to the accompanying drawings- As stated, the plaque base ispreferably composed of copper or a cop'per alloy and the the silver orprecious metal-plating for the surface is indicated at 7. Silver-platingthe surface'by electro-plating isthe preferred 55 method and after thesurface has been plated a shadow material such as lampblack or very nelypowdered carbon, for example, is spread upon the surface as indicated at8 in Fig. 2 and fills the depressions and crevices 00 to accentuate theembossing of the objects in the reproduction. After this powderedsubstance has been spread upon the finished surface of the plaque, asexplained, it is brushed off, but in this `process the minute grains ofG5 the powder adhere to the finished surface of the plaque in thedepressions and orevices to produce a shadowing effect which greatlyincreases the attractiveness of the plaque.

` While I have illustrated and described the preferred form ofconstruction for carrying my invention 'into effect, this is capable ofvariation and modification without departing from Vthe spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails ofconstruction set forth, but desire to avail myself of suchvariations and modificatlons as eome'within the scope ofthe appendedclaims. l

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. The process of making pictorial reproductions rn metal plaque formwhich consists m preparmg a base member in` embossed relief, havingportions raised proportionately to the pictorial reproduction beingmade, and having depressions formed between the raised portions, platingthe surfaceI with a metal coating, covering the plated surface witlra'9o powdered substance to ll said depressions, and then brushing thesurface to remove surplus powdered material, leaving said material inthe-.depressions to accentuate the relief.

, `2.`The process'of making pictorial repro- (95 ductions in metalplaque form which consists in preparing a base member in embossedrelief, having portions raised proportionately to the pictorialreproduction being made,l and having depressions formed between theraised portions, plating vthe surface with a precious metal, coveringthe plated surface with a powdered substance to fill said depressions,and then brushing the surface to remove surplus powdered material,leaving said material in the depressions to accentuate the relief.

3. The process of making pictorial reproductions in metal plaque formwhich consists in forming a base member of malleable metal in embossedrelief, having portions raised proportionately to the pictorialreproduction being made, and having depressions formed between saidraised portions, electroplating the surface with a coating of metal,then spreading .finely powdered carbon or lampblack upon the surface -tofill said depressions, and then brushing off the surplus powderedmaterial but allowing said material to remain in said depressions toaccentuate the relief. a

4. The process of making pictorial reproductions in metal plaque formwhich consists in forming a base member of copper or copper alloy inembossed relief, having portions raised proportionately to the pictorialreproduction being made, and having depressions formed between saidraised portions, electroplating the surface with a coating of preciousmetal, then spreading finely powdered carbon or lampblack upon thesurface to fill said depressions, and then brushing off the surpluspowdered material but allowing said material to remainin saiddepressions to accentuate the relief.

In testimony whereof I have signed my name to this specification.
